Frequently Asked Questions
Does my signature look professional?
Yes! We use high-resolution vector rendering for drawn signatures and premium cursive fonts for typed names, ensuring a clean, executive look.
Is there a file size limit?
Since the processing happens in your browser, the only limit is your device’s memory. Most standard PDF files up to 50MB work smoothly.
